CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 236,263, dated January4, 188.1.

Application iiled November 18, 18510. (Modei.)

To all whom it may concern:

Be it known that d, kEDWARD MOULTON RICHARDSON, of Laconia, in thecounty of Belknap and State of New Hampshire, have invented a new andusefullmprovement in Car-v sectional side elevation taken through theline y y, Fig. 2. Fig. 4 is a front elevation. Fig. 5 1s a sectional endelevation taken through the line z z, Fig. 3.

Similar letters ot' reference indicate corresponding parts.

rIhe object of this invention is to furnish car-couplings so constructedthat the cars can be coupled and uncoupled without its being necessaryfor the attendant to go between the cars, and which shall be simple inconstruction and reliable in operation.

The invention consists in constructingacarcoupling of a coupler-headhaving a longitudinal;l perforation and side slots, a bar sliding in thelongitudinal perforation, a cross-bar attached to the sliding bar andworking in the cross-slots, pivoted horizontal bars, pivoted triangularlever-plates, pivoted upright bars, a cross-har carrying thecoupling-pin, and a push-bar placed in the rear part of the longitudinalperforation, so thatthe cars can be coupled automatically as they arerun together,

' and can be uncoupled by moving the sliding bar forward, as will behereinafter fully described.

1D the accompanying drawings, A represents the coupler-head, which isconnected with the carin the ordinary manner, so as to serve asadraw-bar and as a bumper-head. The coupler-head A is made with ahopper-shaped mouth, B, to guide the end of an entering link into place,and has a central perforation,C, formed longitudinally through it toreceive the short rod or bar D. The bar D is placed in the perforationC, and to its middle partis attached the middle part of a cross rod orbar, E, the ends of which project through short longitudinal slots, F,formedin the sides ofthe coupler-head A, as shown in Figs. l, 2, and 5.

To the ends of the cross-bar E are pivoted the rear ends of two shortbars, G, the forward ends of which are pivoted to the triangular platesH at or near the rear angles of the said plates. The triangular plates Hare pivoted at their upper angles to the sides of the coupler-head A.

If desired, the triangular plates H can he made in the form ofthree-armed levers; but

I prefer the plates as being stronger.

I'Io theforward angles ofthe triangular plates H are pivoted the lowerends of two short upright bars, I, the upper ends of which are pivotedto the ends of the cross-bar J.

The sides of the coupler-head A are recessed to receive the bars Gr Iand triangular plates H, so that the said bars and plates will beprotected from accidental injury. of the forward end of the'coupler-headA is recessed to receive and protect the cross-bar J and to keep thesaid cross-bar in place as it moves up and down. In the center ofthecross-bar J is formed a hole toreceive the coupling-pin K, the head ofwhich rests upon the upper side ot' the said cross-bar J, so that thecouplingpin Kean be raised and lowered by raising and lowering the saidcross-bar J. In the rear part ofthe perforation Gis placed a har, L,which slides freely within the said perforation. The rear end of the barL pro jects at the rear end of the coupler-head A.

The bar L may he placed loose in the coupler-head A, and arranged tostrike against a part of the car-frame, or against a suitable stopattached to the car-frame; or the bar L can be rigidly attached to thecar-frame. In either case, as the cars are run together the linkattached to the coupler-head of one car will enter the mouth B of thecoupler-head A of the other car and push the said couplerhead back uponthe bar L, which causes the forward end of the bar L to press the bar Dforward and operate the bars and plates G I J H to raise thecoupling-pin K, which coupling-pin, as the coupler-head A is pushedforward by its spring,l drops through. the lilik and couples the cars.

The coupling is designed to be provided with levers, which may beconnected with the ends of the cross-har E, or with the ends ot' thecross-bar J, or with the push-barkas may be desired or convenient7 andwhich project The upper side IOO into such positions that they can bereached and operated from the sides of thecars to raise the coupling-pinK to uncouple the cars, which levers are not shown in the drawings. Achain can be attached to the coupling-pin K 0r to the cross-bar J, andextended to the top ot the car, so that the cars can be uncoupled fromthe top of the car, if desired.

Having thusdescribed my invention, I claim as new and desire to secureby Letters Patent- 1. A car-coupling constructed substantially as hereinshown and described, consisting ot the coupler-head A, having alongitudinal perforation, C, and side slots,F, the sliding bar D, placedin the perforation G, the cross-bar E, attached to the sliding bar D andworking in the slots F, the pivoted horizontal bars G, the pirotedtriangular lever-plates H, the pivoted upright bars I, the cross-bar J,the couplingpin K, and the push-bar L, placed in the rear part of theperforation C, as set forth.

2. In a car-coupling, the combination, with the coupler-head A, havinglongitudinal perforation C and side slots, F, and the couplingpin K, ofthe sliding bar D, the cross-bar E, the pivoted horizontal bars G, thepivoted triangular lcver-plates H, the pivoted upright bars I, and thecross-bar J, substantially as herein shown and described, whereby thecoupling-pin can be raised by the forward movementof the sliding bar, asset forth.

3. In a car-coupling, the combination, with the coupler-head A and thesliding bar D and its attachments, of' the push-bar L, substantially asherein shown and described, whereby the said sliding bar and itsattachments will be operated automatically to raise the coupling-pin asthe cars are run together, as set forth.
